IS my phone borked?Support

So I was using the phone, listening to a podcast when the audio started to cut out. The phone was acting sluggish so I rebooted it. Now it stops booting at the slash screen and won't go any farther. I was able to open clock work recovery one time, but the menu key wouldn't work so I couldn't do anything. Another strange thing, the notification light was bright red when I but the battery back in, even without powering on the phone. That light has since turned green. Several more reboots went straight to the download mode screen, but now it just sits at the splash screen no matter what buttons I press. Any idea what happened? So strange that it would fall apart in my hand after nine months of use.
